Islamic terrorists destroyed part of an Egyptian security building at Rafiah Saturday night, challenging Cairo’s control over the Sinai after the ceasefire with Israel. No one was injured in the explosion at the base, under construction n the Egyptians side of Rafiah, the smuggling capital of Gaza.

The attack came 48 hours after Egyptian President Mohammed Morsi granted himself extensive new powers, which were challenged by Cairo’s judiciary.

A separate explosion injured three people further south in the Sinai, where Egypt is building a facility to help it protect the pipeline that ships natural gas to Israel and Jordan. Terrorists have bombed the pipeline more than a dozen times the past two years in an effort to scuttle the agreement to sell gas to Israel.
